Abstract: Apparatus is configured to: receive a current location and a planned destination from a plurality of mobile devices; plan travel routes for each of the plurality of mobile devices, based at least on the current locations and planned destinations, that reduce congestion and/or improve air quality in a geographical area, and communicate the planned travel route to the associated mobile device.

Abstract: A method of controlling a range extender of an electric vehicle comprises using actual measured or modelled pollution levels dynamically to set a target state of charge level for a range extender of an electric vehicle at a particular location.

Abstract: This invention relates to an apparatus for controlling a range extender (104) in an electric vehicle (100). The apparatus comprises means for receiving trip information, means for retrieving power usage information relating to a previous trip, the previous trip having trip information which is at least in part in common with the trip information; and means for activating the range extender (104) in dependence on said power usage information. The invention also extends to an associated method, computer product and system.

Abstract: A range extender for a vehicle, comprises an electric machine; an engine; and a controller, wherein the controller is configured to control fuelling of the engine, and is configured to control the electric machine to charge a battery of the vehicle using power from the engine and at other times to control the electric machine to drive the engine using power from the battery, wherein the controller is configured to increase the engine speed by controlling the electric machine to drive the engine using power from the battery whilst substantially not fuelling the engine.

Abstract: A system and method for advertising and content presentation in the sky. An artificial cloud is created by an aircraft, which adds water vapor and particles to the atmosphere and color if desired. The artificial cloud or alternately, a natural cloud is used as a background for delivering a visual image. This can be achieved by projecting an image onto the cloud by either laser or visible light sources. Projection of the image is preferably performed from an aircraft. The artificial cloud or alternately, a natural cloud can be used as a base for cutting the cloud into the shape of the image, which is performed by dissipating the cloud from an aircraft, or alternately an image shape can be cut out of the cloud. This method can be exploited for clearing clouds in places such as above an airport in order to increase navigational visibility.
